Title:
DRIVING ASSEMBLY MANAGEMENT SYSTEM, FAULT DETECTION METHOD, AND ELECTRIC POWER-ASSISTED BICYCLE
Document Type and Number:
WIPO Patent Application WO/2023/071638
Kind Code:
A1
Abstract:
A driving assembly management system, a fault detection method, and an electric power-assisted bicycle. The driving assembly management system comprises: an Internet-of-things device (100), multiple digital assemblies (200), and a bus (300); each digital assembly (200) comprises: a driving assembly (201) and a digital circuit (202) connected to the driving assembly (201); the digital circuit (202) comprises: an assembly signal processing circuit (203), a first processor (204), and a first memory (205); an input end of the assembly signal processing circuit (203) is connected to a signal acquisition end of the driving assembly (201); the first processor (204) is further connected to the assembly signal processing circuit (203); the first memory (205) is connected to the first processor (204); and the Internet-of-things device (100) is communicatively connected to the first processor (204) in the multiple digital assemblies (200), so as to perform fault detection according to working state data and identification information of the multiple digital assemblies (200). According to the present system, fault detection can be performed according to the acquired working state data and identification information without manual determination, such that a driving assembly in an electric power-assisted bicycle is easy to maintain.
